probability | R Documentation |
These convienience functions make it easier to compute transition probabilities from indidence rates, OR, RR, or probabilities estimated on a different timeframe.
rescale_prob(p, to = 1, from = 1) prob_to_prob(...) rate_to_prob(r, to = 1, per = 1) or_to_prob(or, p) rr_to_prob(rr, p)
p |
Probability. |
to |
Compute probability for that timeframe. |
from |
Timeframe of the original probability. |
... |
For deprecated functions. |
r |
Rate. |
per |
Number of person-time corresponding to the rate. |
or |
Odds ratio. |
rr |
Relative risk. |
A probability.
